CYRUS W. SALADEE, OF WASHINGTON, DISTRICT OF COLUMBIA.

ROAD-WAGON.

SPECIFICATION forming part of Letters Patent No. 228,397, dated June 1, 1880.

Application filed March 31, 1880. {N0 model.)

To all whom it may concern Be it known that I, CYRUS W. SALADEE, of Washington city, in the District of Columbia, have invented certain Improvements in Road- "Wagons, of which the followingis a specification embodying my said invention.

To enable others skilled in the art to make and use my invention, I herewith submit the following general description.

My invention relates to that class of roadwagons in which longitudinal semi-elliptic springs arranged upon different horizontal planes connect the axles as well as constitute the spring-platform and my invention consists in connecting and combining the springs, as hereinafter described. and in the application of one or more spring-braces, so as to prevent side motion and'secure greater flexibility.

In the drawings forming part of this specification, Figure l is a side elevation, in part section, of the runninggear of a road-wagon, showing my improvements; Fig. 2, a plan of the same; Figs. 3 and4, views showing modifications, Fig. 5, a side view, showing a form of leaf-springs.

AAare the side springs, connecting, in the present instance, the rear axle, G, and the bolster H, and B is a central spring connecting the rear axle and bolster, but arranged upon a lower plane than the side springs. Each spring A is composed of leaves 1 2 3 4, as shown in Fig. 1. The springs are hinged to the bolster and axle in any suitable manner.

The springB is braced by one or more braces, O, which, in Fig. l, is arranged in a plane below the spring B, hinged at its front end near the central portion of the front axle, bent into a loop at the inner end, and connected to the spring B above. The central spring, B, constitutin g the perch, and the spring-brace G are each of a single plate of steel, and are crossbraeed by braces H H (shown in Figs. 1 and 2 as connected to the spring-brace and in Figs. 3 and 4. as connected to the perch.)

The spring-brace may extend to the rear instead of the front, or two may be used below the perch, as in Fig. 3, or the perch may be placed in a lower plane and the spring brace or braces arranged above, as shown in Fig. 4. In any event the brace or braces impart addiconsisting of several plates constituting a leafspring. After extended experience with both these arrangements, I have found that with the former the spring-platform is too rigid, and that when only leaf-springs are used, although greater flexibility was secured,'there was such a lateral play of the leaves of such springs one upon the other, resulting from side thrusts, that the side motion was permitted to a very deleterious extent. As a means of preventing such side play of the leaves, I applied box-loops over the ends inclosin g the entire body of the spring, or formed the leaves with lips s s, as shown in Fig. 5; but Ifound both alike defective, the loops retarding the free action of the leaves and the lips snapping off under the severe lateral strain.

By the above-described construction I prevent the side motion without in the least interfering with the freedom of action in each spring. This results from using a spring-perch, B, consisting of a single plate of steel, in connection with the leaf-springs, and bracing the whole laterally together, the single platesprings preventing the lateral movement to which leaf-springs are liable, while the latter insures the desired flexibility.

It will be apparent that the combined leafsprings may be differently arranged and the number of springs varied as circumstances may require.

While the above-named features have been described asimprovements on my triple-spring wagon, as aforesaid, I wish it to be understood that they are applicable to various other wagons, and it is my purpose to employ them in such connections. 4

I claim- 1. The combination, with the leaf-springs of a spring-platform, of one or more sin gle-plate springs, combined and braced with the leafsprings, substantially as set forth, to limit the side motion of the latter, as specified.

2. The combination of the springs A A and 5 central spring,]3, arranged in a difi'erent plan e, and cross-braces, one or more of said springs being made of a single plate and the others of superposed leaves, substantially as set forth.

3. The combination, with the spring-perch B, 10 of one or more spring-braces, consisting each of a strip connected at one end near the center of the axle and bent at the inner end and connected to the spring B, substantially as set forth.

In testimony of my claims to said invention 15 I hereunto subscribe my name. CYRUS WV. SALADEE. Witnesses:
